The awkward shuffling and lunging that happens when one attempts to walk accross the path of a slow-moving car (usually in a parking lot). The pedestrian, in an act of benevolence, signals for the car to keep going, only to be waved on by the driver. Both the driver and the pedestrian then wave to thank the other, both thinking that it is there turn to go. Both go, only to realize the other is moving as well. What follows is a series of false starts by both parties. The driver's actions are similar to those involved in "yoking
the whip", yet are in a completely different context and have a completely different rationale.
